Definitions

  • FIG. 4 shows further details of the sensing unit 26.
  • the photosensitive element chips 36 and the LEDs 32 are mounted directly on a ceramic substrate 60 in recess 62. Mounting the photosensitive element chips 36 in this manner, rather than utilizing dual-in-line packaged chips, means that a level of packaging can be eliminated in the device.
  • Standard attach wires 64 are used to connect the chips 36 to conductive patterns on the ceramic substrate 60 in a conventional manner.
  • a transparent layer 66 of a plastic or other suitable protective material is deposited over the chips 36 and diodes 32.
  • Collimating fiber optic plates 68 consisting of short optical fibers 69 are positioned over the photosenstive elements of the chips 36.
  • Amplifier 142 amplifier the light/dark signal outputs from the array 34.
  • 8chmitt trigger 146 turns the amplified analog signal from amplifier 142 into a square wave at an adjustable threshold. Adjusting the threshold gives contrast control for the scanner 20.
  • the data gate 124 measures the time between start pulses. When the time between start pulses is greater than 40 milliseconds, data gate 124 turns the data off for one line scan. This is necessary due to dark current from the array 34.
  • software for analyzing the digitized images obtained with the scanning device 20 is run on the personal computer or other data processing system to which the scanning device is attached.
  • sophisticated analysis of the images may be carried out, such as optical character recognition, while keeping the scanning device 20 simple in construction.
  • the scanners described above are capable of digitizing text and graphics in printed form for use in data processing systems.
  • the structure of the scanner insures that it is moved across a sheet of text or graphics in a straight line path.
  • Commercially available sensor chips 36 each less than a page width are arranged in the scanner so that a full page width can be scanned in a single line scan, without requiring the use of a lens system.
